I haven't dived into the Bermuda Triangle questions yet, but your last sentence made me smile:
As a very young child, I perused my father's book shelf and "stole" adult books to read in bed at night ...
HaHa!! I did exactly the same, and oh, what books I found in my older sister's and brother-in-law's closet! Memories of reading forbidden for teenagers come back. I read a booklet that could be described as quite scandalous. And there I also discovered my first interest in SF with - as it seemed to me at the time - the complete edition of all Perry Rhodan books.
